Basic Facts & Resources

Also reported earlier on this blog entitled “Barnett Shale Gas Drilling Contributes to Air Pollution,” WFAA-TV’s March 12, 2009 telecast interviewed SMU professor Armendariz and gas industry spokesmen about the professor’s claim that gas drilling pollutes as much as all cars and trucks in the metroplex.


As reported earlier on the blog, The Endocrine Disruption Exchange (TEDX) is a good source of information related to endocrine disruption—health and environmental problems caused by low-dose exposure to chemicals that interfere with child development and function.  Contrary to the propaganda of the oil and gas industry, data is presented that refutes this industry’s misinformation. 


Air pollution from natural gas drilling in the Barnett Shale produces nearly as much air pollution as all the cars and trucks in the Metroplex, reports the Fort Worth Star-Telegram.  According to a study by , pollution from the 7,700 wells is centered on the highly populated area.  However, the researchers say the pollution can be easily controlled with existing technology. 


When the oil and gas industry was granted an exemption in 2005 from the federal Safe Drinking Water Act, the fresh drinking water from underground sources is being threatened by toxic chemicals used in oil and gas drilling/production.   Americans get half of their fresh drinking water from underground sources.  This exemption prevents regulation and control by the U.S. Environmental Protection Agency.  Furthermore, because oil and gas companies are not required to report the volumes and names of chemicals being injected during hydraulic fracturing at state levels, neither the government nor the public can evaluate the potential health risks.  More information about these chemicals can be found at:  chemical.html


On December 28, 2008 the Denton Record Chronicle launched its five-part series exploring urban gas drilling and gas boom bringing potential dangers closer to homes.  Texas in tug-of-war between underground mineral resources and the people who live on the surface are described in the third part on December 30. The Denton Record Chronicle’s fourth part on December 31 reports observations and studies showing subtle, long-term effects of gas drilling.  In its last of five parts, the Denton Record Chronicle describes the opponents as well as the backers of gas wells taking up life-altering Argyle-area neighborhood’s struggle against it.  The Denton newspaper reports that the expansion of natural gas industry into Barnett Shale leaves Argyle families with little recourse because of the dominance of the gas drilling companies.  Then the second part on December 29 reported about the


Nearly 10,000 producing gas wells have been drilled in the Barnett Shale region and thousands more have been permitted by the Texas Railroad Commission. In Fort Worth alone, over 1,000 natural gas wells have been drilled inside the city limits within the past three years, dramatically increasing air pollution by at least three-fold, according to a peer-reviewed study by Dr. Al Armendariz, of Southern Methodist University.  As he pointed out in a recent lecture, Barnett Shale drilling activities are the largest source of smog (NOx and VOC), greenhouse gases and air toxic compounds in North Central Texas.


Although gas drilling companies keep their fracturing “formulas” private, the Pennsylvania Department of Environment Protection supplied a list of chemicals used in the process.  Any of these chemicals may be present in wastewater generated and are stored temporarily in open pits at the drilling site.


The Fort Worth Star Telegram reported on December 4, 2008 that the number of drilling rigs working in the Barnett Shale has fallen to its lowest level in about two years as energy companies pull back in the face of lower natural gas prices.


The Endocrine Disruption Exchange, Inc. (TEDX) is the only international organization that focuses primarily on the human health and environmental problems caused by low-dose and/or ambient exposure to chemicals that interfere with development and function, called endocrine disruptors. TEDX’s work focuses on the endocrine system, which is the exquisitely balanced system of glands and hormones that regulates such vital functions as body growth, response to stress, sexual development and behavior, production and utilization of insulin, rate of metabolism, intelligence and behavior. Their research was designed to explore the health effects of the products and chemicals used in drilling, fracturing (frac’ing, or stimulation), recovery and delivery of natural gas. TEDX’s website provides a glimpse at the pattern(s) of possible health hazards for those living in proximity to gas development. In the process of researching the literature, they discovered that drilling companies have access to hundreds of products, the components of which are in many cases unavailable for public scrutiny. Their research papers cover oil and natural gas development in Colorado, Montana, New Mexico, Washington and Wyoming.  For example, their report about gas development in Washington claimed that 68 products used in gas production contained at least 88 chemicals.  All of these products have adverse health effects.


Experts at the University of Colorado’s School of Public Health’s Department of Environmental and Occupational Health completed a review of hundreds of published, peer-reviewed scientific articles to examine what is known concerning the health effects of oil and gas drilling and production on neighboring communities.  Two resulting papers–Literature Review–are convincing evidence of threatening health problems caused by oil and gas drilling.A White Paper and

We have felt the pollution and seen it in Clearville, PA. Pennsylvania residents need educated as well as those who enact laws which will pollute Pennsylvania’s air, water and soils.
Too many laws passed by those who hear the good side of what natural gas production. What is missing in this reply from a PA State Representative, and how would you reply to it?
